Not exactly what we might think of as the draft but the US is does not have an all volunteer army:

To many of the soldiers whose retirements and departures are on ice, however, stop-loss is an inconvenience, a hardship and, in some cases, a personal disaster. Some are resigned to fulfilling what they consider their patriotic duty. Others are livid, insisting they have fallen victim to a policy that amounts to an unannounced, unheralded draft.

Congress should immediately repeal their mistake:

Congress approved the authority for what became known as stop-loss orders after the Vietnam War, responding to concerns that the military had been hamstrung by the out-rotations of seasoned combat soldiers in Indochina.

In a country based on freedom, on the concepts of life, liberty and the pursuit of happiness slavery must not be allowed to exist.

Update (12/29): Craig Cheslog has a good post on this. I disagree, though, with one point he makes: While the government has the right to treat our soldiers this way,… Nope, we should not grant the government any such right. The government is our servant not our master.
